VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 464,627, dated December 8, 1891.

Application filed March 2, 1891. Serial No. 383,405. (No model.)

To all whom it may concern;

Be it known that we, EARL A. THIssELL and WILLIAM H. WILDER, citizens of the United States, residing at Florence, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improve ments in Vapor-Burners; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in vapor-burners, and more particularly of the type set forth in patent to W. R. Jeavons, No. 438,548, dated October 14, 1890, the object be ing to provide a convenient and easy mode of adjustment to the burner-bowl for the purpose of initial starting.

To this end the invention consists in the construction and arrangement of parts, substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical central sectional view of a burner embodying the novel elements of the invention. Fig. 2 is a perspective view of the in side tube and the vaporizing-bowl rigidly secured thereto. Fig. 3 is a perspective View of the hinged base for said bowl and tube, and Fig. 4 is a perspective View of a rocking frame adapted to pivot on the center of the hinged base in lieu of the balance and rocking bar shown in Fig. 3 and of the projections on the cross-bar shown in said view. Fig. 5 is a plan view of the top skeleton frame.

A represents the outer perforated tube, and B the top fixed frame to which the said tube is secured. This frame is preferably made in skeleton form, so that there will be as little heat as possible conducted away from the inner rim or ring portion of the frame, which forms a partial cover for the vaporizing-bowl, to the outer portion of the frame, where it would be dissipated. To this end only a few connecting bars or webs b are employed between the inner and the outer portions of the said top frame B, and the remainder of the space is open. Of course this construction go'may be considerably varied and still keep within the spirit of the invention. It will be understood that the frame B is fixed andstationary on the stove-frame.

0 represents the burner or vaporizing-bowl, provided in its bottom with two concentric grooves separated by a slightly-raised rib o, and a strand or wick c of any suitable noncombustible material is shown in the inner groove. This wick is in the inner groove and inside of the cover B, as seen in Fig. 1, because it is employed only for initial lighting or starting of the burner and performs no office whatever in maintaining a flame when the burner is once under headway. The inner combustion-tubeDis securedrigidly tothe inner edge of the bowl 0, as is now well known in this art, andwhen the bowl is in regular working position its outer groove is substantially covered by the rim or frame B, so as to produce a chamber between said parts for the equal distribution of the vapor and the production of equal combustion at all points between the tubes A and D.

The bowl (J, for convenience of initial lighting, as well as for other reasons, is supported from below on an adjustable frame E. Thisframe is preferably made to conform to the circular outline of the burner, and at its center has a cross-bar G, on which, in Fig. 3, isa balance or rock bar H, and in Fig. t a spider K, designed to substitute the bar H, if preferred. The bar H or the spider K is pivotally secured on the support G, so as to accommodate the lifting mechanism to any inequalities in the contact-surface between the bowl 0 and the inwardly-projecting rim of frame B,against which it bears from below when in working position, the joint between these parts being close so as to not admit air from the outside. If the support for the bowl were rigid throughout, it might bear upward more forcibly on one side than the other, and thus possibly expose one side of the burner to airdrafts between the bowl and its cover, and thus cause the burner to emit more or less a yellow flame and greatly impair combustion; but by employing a pivoted or balancing rest as the immediate support of the bowl the frame E may incline more or less one way or another and yet serve through said balance.

In Fig. 3 the balance-bar His shown as having t-wo guide-posts 71 while two other guidero posts 72 are rigid with the cross-barG. These come inside the bowl C and serve to keep it centered in its up-and-down movements. a like purpose and contributing to the guiding and supporting of the bowl and the tube D, fixed thereto, the said tube has projections d at its top, which bear against the outer tube and are adapted to slide thereon when the tube D is tilted and moved in either direction.

For convenience and ease in making the adjustments referred to, the frame E is provided 2 5 down toward the fulcrum on its rollero when the parts are lowered, as seen in dotted lines. A sliding weight or its equivalent in mechanism might be employed, and when the countor-balance assumes the latter position the 0 parts will remain down until restored to working position by hand. In the lowered position the wick c is brought directly beneath the drip of the oil-supply pipe P, and oil for initial starting is then supplied to said wick 5 and a light applied thereto, after which the parts are immediately raised to working position.

R is an inverted cone or hood with an aperture at its lower portion for the admission of This hood may be made of the same piece as the frame E or an extension thereof ,fastening to it by any suitable means. This aperture through its bottom is made of such size as to admit the proper amount of air to On account of the inclination of the sides of the hood, as shown, the interior of the burners is protected from drafts and air-pu flfs, which might seriously interfere with the smooth operation of the burner. Again,

the inclination of the hood is such that the 5 5 vaporization of the oil.

. To operate the burner, bear down on the lug e on frame E, when the parts will assume the position shown in dotted lines, Fig. 1 In this movement the lever II will rise, as shown, the

weight 0 move toward the center, and the parts remain at rest in that position. In this movement the bowl 0 has lowered and moved toward the supply-pipe so that theinner concentric channel containing the absorbent is di- Then turn on the oil, which will now drop on the wick or absorbent. By lifting on the lug e the parts are restored to the operative position, and the oil will then drip into the outer concentric channel of the bowl. Meantime the oil on the absorbent is burning to heat this outer channel to a vaporizing condition.

hen it is desired to remove the bowl 0 for cleaning or the like, the parts are lowered, as hereinbefore described.

The hood B may be constructed and arranged as here shown, so as to provide an opening at its bottom for the admission of airto the burner, or itmay be perforated more or less for this purpose. If perforated, the bottom might be closed, except as perforations might be formed thereon for ventilation, as herein described.

Again. to prevent air-drafts from interfering with the operations of the burner, a hood R is arranged about the upper part of the burner and encircles the combustion-tubes. This hood preferably converges from its base to its top, which rests against the outside tube, and preferably is imperforate, so as to exclude air, except as it is drawn in from beneath through the lower hood. The lateral projections d on the inner combustion-tube, at its top, might have a ring connected with their extremities which would bear against the outer tube and take the lateral pressure when the tube is adjusted. This ring might have any form that would serve the purpose. The balance-bar H might be rigidly or otherwise connected to the burner-bowl and pivoted on the bar G, substantially as here shown,or in any equivalent way.

Having thus described the invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a vapor-burner, the pivoted supporting-frame, the vaporizing-bowl, and an intermediate balance on which the bowl rests, sub stantially as described.
